Rashi says there were 13 and the Meforshim argue about which two he left out and why.
• The Mizrachi says the three types of wool were only counted as one.
• The Maharal MiPrague says that the Avnei Shoham and Miluim were not counted because the Nesi'im brought them.
• The Sefer Zikaron says that the Oros Eilim and Tachash were counted as one and so were the two precious stones Shoham and Miluim.
• The Tzemach Tzedek says that we don't count Oil and Fragrances since they were for the Avodah and not the building.
